Alright, let's solve this math problem step by step. First, we have the number 103. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 42. So, we're going to take the number 103 and add it to itself 42 times.
Step 1: 0 + 103 = 103
Step 2: 103 + 103 = 206
Step 3: 206 + 103 = 309
Step 4: 309 + 103 = 412
Step 5: 412 + 103 = 515
Step 6: 515 + 103 = 618
Step 7: 618 + 103 = 721
Step 8: 721 + 103 = 824
Step 9: 824 + 103 = 927
Step 10: 927 + 103 = 1030
Step 11: 1030 + 103 = 1133
Step 12: 1133 + 103 = 1236
Step 13: 1236 + 103 = 1339
Step 14: 1339 + 103 = 1442
Step 15: 1442 + 103 = 1545
Step 16: 1545 + 103 = 1648
Step 17: 1648 + 103 = 1751
Step 18: 1751 + 103 = 1854
Step 19: 1854 + 103 = 1957
Step 20: 1957 + 103 = 2060
Step 21: 2060 + 103 = 2163
Step 22: 2163 + 103 = 2266
Step 23: 2266 + 103 = 2369
Step 24: 2369 + 103 = 2472
Step 25: 2472 + 103 = 2575
Step 26: 2575 + 103 = 2678
Step 27: 2678 + 103 = 2781
Step 28: 2781 + 103 = 2884
Step 29: 2884 + 103 = 2987
Step 30: 2987 + 103 = 3090
Step 31: 3090 + 103 = 3193
Step 32: 3193 + 103 = 3296
Step 33: 3296 + 103 = 3399
Step 34: 3399 + 103 = 3502
Step 35: 3502 + 103 = 3605
Step 36: 3605 + 103 = 3708
Step 37: 3708 + 103 = 3811
Step 38: 3811 + 103 = 3914
Step 39: 3914 + 103 = 4017
Step 40: 4017 + 103 = 4120
Step 41: 4120 + 103 = 4223
Step 42: 4223 + 103 = 4326

So, 103*42 = 4326
